From a5d79d1e4fa58e12a37c91963fc071d811d2cffd Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Tue, 13 Feb 2007 16:56:21 -0600 Subject: [PATCH] [PATCH] bcm43xx: OFDM fix for rev 1 cards Nearly all of the writes to the bcm43xx internal lookup tables (ilt) involve 16-bit quantities. Accordingly, the ilt_write routine was coded to pass a u16 value. For one early GPHY chip, 32-bit quantities are needed. For those writes, the value was clipped to 16 bits. This patch adds an ilt_write32 routine that receives a 32-bit quantity and writes it to the appropriate locations. Signed-off-by: Larry Finger Signed-off-by: John W.
